eBay is offering the Waterproof Bluetooth Speaker Portable Wireless Shower Radio for only $7.99 shipped. That’s $15 less than any other waterproof/shower speaker we could find and the lowest we’ve seen.
The speaker has a built in suction cup so you can stick it anywhere. White Boards, Showers, or any flat surface. The speaker works on a 2.4Ghz radio frequency and has a battery life of 7 hours for music playback and 5 hours for talk time. There are 7 colors to choose from and a 1 year warranty applies.
About $.38 cents more at Amazon where it gets 3.5/5 star – most of the 1 stars being complaints about delivery times.
